Drilling Update
Further positive results from the In Gall license area, Niger
Niger Uranium, the uranium focused exploration and investment company with
interests in Niger and Namibia, is pleased to announce its initial downhole
radiometric logging results for the drilling programme on the Company's 100%
owned In Gall license in Niger.
Highlights
•Drilling at Niger Uranium's In Gall license, at target 17 has delineated
a near surface uranium-mineralized layer with dimensions of 5,000 metres by
900 metres and open to the west.
•Radiometric probe data shows the layer has an average thickness of 1.2
metres and a grade of 122 ppm eU3O8 based upon data from 32 boreholes
drilled on a 250 by 400 metres grid.
•The probe data shows that grade and thickness is very consistent; the 32
intersections ranged from 63 ppm eU3O8 over 0.7 metres to 177 ppm eU3O8 over
1.8 metres. Results of XRF analysis on samples collected from the same
boreholes indicate higher grades, up to 238 ppm U3O8 over 2.0 metres.
•The layer is gently dipping and exposed at surface and historical data
suggests this zone extends over 15 kilometers to the west of the area
drilled to date, highlighting the potential for a considerable open-pittable
resource.
•At other target areas within the Company's In Gall and Irhazer Licenses,
a survey comprising 1,500 radon detectors will be completed by Stratamodel
of the USA. Results from this survey are expected to delineate 'concealed'
uranium deposits that may be present along major structures. In the interim,
step-out drilling will commence at target 10 where an earlier lone
scout-drilling borehole highlighted an intersection of 9.2 metres grading
105 ppm eU3O8.
Ian Stalker, Deputy Chairman, said:
'The identification of such a large mineralized area at this early stage in our
drill programme is an exciting result. Our objective is the identification of an
economically viable uranium resource in Niger and we look forward to informing
shareholders regarding the ongoing work programme as soon as results are made
available.'
A 10,000 metre drilling programme commenced in January 2008 and to date 4,100
metres have been completed. Drilling has focused on target 17 where a
mineralized layer 900 metres wide, with a minimum strike length of 5,000 metres
and potential for significant extension in a westerly direction, has been
identified. Niger Uranium plans to complete several step-out fence lines to
extend the currently delineated mineralized area.
At target 17, the uranium is hosted in proximity to the contact between oxidized
sandstones of the Tegama Formation and reducing mudstones of the Irhazer
Formation, within the Tim Mersoi Basin. The proximity to surface, continuity of
the mineralization and gentle dip (between 2 and 5 degrees to the southwest)
support in-situ leaching or open-pit mining as a potential extraction technique.
Visual observation of material exposed in trenches suggests that carnotite is
the dominant uranium mineral occurring as growths and coatings on fracture
surfaces.
Drilling is being carried out by Esafor Drilling under the supervision of MSA
Geo Services of South Africa. All boreholes are vertical and drilled by the
tri-cone method and probed using a Robertson Geologging gamma tool, calibrated
by Terratec Geoservices in Germany to provide equivalent uranium grades
expressed as eU3O8. To support the probe data, borehole samples were sent to SGS
Lakefield for XRF analysis for U3O8. The XRF results are contained in appendix
2. Samples were all one metre in length and taken at mineralized intervals as
indicated by the probe data. The XRF U3O8 grades are significantly higher than
those obtained from radiometric probing for the same intervals. This is most
likely to be a result of positive disequilibrium which results in the
underestimation of grade if determined by radiometric probing. If this is
verified by additional drilling and sampling, a significant increase of grades
reported in appendix 1 can be expected.
To advance the other targets within the In Gall and Irhazer Licenses, the
company will commence drilling late in April 2008 to follow up on surface grab
samples which returned up to 0.98 % U3O8, as reported on 29 January 2008. At
target 10, a ground magnetic survey was completed to assist with the positioning
of 4 step-out holes along strike and down dip of AB003 which intersected 9.2
metres grading 105 ppm eU3O8 from 190.9 metres depth, as indicated by
radiometric probing. At other targets a survey using 1500 CR39 radon detectors
will help define drill targets along major structures identified from satellite
and airborne radiometric data. The CR39 film detects radon emanating from
concealed uranium mineralization.

GLOSSARY
uranium Uranium is a silver grey moderately radioactive metallic element that
has the symbol U and an atomic weight of
In-situ In-situ leaching (ISL) or solution mining is a process of recovering
leaching minerals such as copper and uranium through boreholes drilled into the
(ISL) deposit. Explosive or hydraulic fracturing may be used to create open
pathways in the deposit for a solution to penetrate. Leaching solution
is pumped into the deposit where it makes contact with the ore. The
solution bearing the dissolved ore content is then pumped to the
surface and processed.
Tri-cone A rapid, relatively cost effective technique of drilling boreholes for
drilling uranium exploration by gamma ray probe. The tri-cone drill (or roller)
bit, consists of three cone shaped toothed rollers in a cluster. Each
of the cones has hard teeth mounted on bearings. The spatial control of
sampling for laboratory purposes is not good with tri-cone drilling and
alternative drilling techniques would have to be used.
CR39 Is a technique of soil survey to measure or detect buried uranium
radon mineralization in certain geological environments.

U3O8 The uranium content of a sample is reported as U3O8 if the analysis is
performed in a laboratory. Uranium content when measured by a gamma ray
down hole probe is reported as eU3O8.
